DENTAL CHAIR HEADREST COVER Application filed October 2, 1929. SerialNo. 396,859.

This invention relates to accessories for dental chairs and the like andparticularly relates'to a sanitary coveringmeans for the head-rests ofsuch chairs.

The general object of this invention is to provide an improved sanitarycover for the head-rest cushions of dental chairs which is simple inconstruction, easily and quickly applied and removed, economical ofmanuib facture, and easily laundered.

Further objects and advantages of the present invention will becomeapparent from a study of the following specification and appendeddrawings, in which Fig. 1 is a view in perspective showing the head-restof a dental chair with the headrest cover in place.

Fig. 2 is a transverse section through the head-rest cover showing themanner in which 2 the head-rest cover protects the head-rest cushions.

Fig. 3 is a plan view of one form of the head-rest cover. I Fig. 4 is asection taken on the line 22 of Figure 3. 1

Fig. 5 is a plan view illustrating a modification of the constructionshown in Figure 3.

Fig. 6 is a section taken on the line 6-6 of Figure 5.

Fig. 7 is a view similar to Figs. 3 and 5, but on a reduced scale,illustrating a further modification.

Figure 1 illustrates the upper portion of i the back of a chair such asis commonly used by dentists or barbers, from the top of which projectsa head-rest which, as shown in Figures 1 and 2, is provided with twoadjustable pads, each supported by an adjustable mem- '40 her which iscapable of adjustment relative to the back of the chair for the purposeof adapting the head-rest to persons having different heights and widthsof head.

It has been found desirable in the dental art to protect the cushions ofthe head-rest for the purpose of preventing transmission of skin andscalp diseases due to contact with persons who may have such diseases.As a sanitary precaution it is customary to cover the cushions with somekind of readily cleanable and replaceable means such as a towel orspecially prepared pad. In some instances paper has been used for thepurpose while in other-cases specially shaped linen covers are provided.

The present invention relates more particularly to such covers forhead-rests of dental or barbers chairs and comprises a sheet offiexiblematerial 1 which, as shown in Figure 3, is composed of a singlesheet of flexible material suchas linen toweling, for instance, foldedzit/2. ,The upper edges and the right and left edges respectively, ofthe'two folded portions thus formed, are turned under and stitched bystitches 3 so asv to form a substantially rectangular envelope. Acentral line of stitches 4; extends from top to bottom, Figure 3, anddivides the rectangular envelope formed by stitching the edges of thehead-rest cover together into two compart ments or pockets. Each of thecompartments or pockets formed by the central stitches 4 is providedwith an opening produced by slitting one of the folds ofthe headrestcover by a vertical slit 5, which, as best shown in Figures 3 and 4, isedged with a suitable material to prevent ravelling.

The cushions of the dental chair head-rest are ordinarily adjustedsomewhat at an angle to each other so that thehead of the personoccupying the chair will lie firmly yet comfortably in the V-shapedspace between the cushions. The central line of stitches 4 serves tomake the head-rest. cover conform to: the angularity of the cushions andthus makes a neater appearance and at the same timeprevents anydiscomfort which might be caused by a badly fitting cover.

The head-rest cover produced in the man- .ner just described is usedby'drawing the .cover over the cushions of the head-rest, this processbeing permitted by the slits 5 which allow the cushions to be slid intothe compartments formed by the central line of stitches 4. The slits 5are of sufficient length to make it easy to draw the headerest. coverover the cushions by manipulating the cover in asuitable manner manuallyuntil the cover is in place as shown in Figure 3, the central line ofstitches 4: serving tocause the headrest cover over the head-restcushions,a-modification is contemplated such, for instanceas is shown inFigures 5 and 6', or as is shown in Fig. 7. The slits 5 are providedwithcem tral enlargements 6 formed by cutting out the material about themid-point of: the slit and edging the slit and the enlargement withsuitable material to prevent ravelling: This central opening makes itpossible to draw tli'eliead-rest cover over thehead restcushionsmoreeasily'andat the same time pre Vents unnecessary stretching ofthem'aterial forming the liea'd rest cover, thus reducing thewear andtear on the head-rest cover. The generally ovate opening characteristic;of Fig; 7" also facilitates applying the cover.

If so desired; the central line of stitches maybe dispensed withalthough it is preferable to so stitch the head-rest cover for thepurpose of causing the head-rest covermore ne'arlyto conform to theangularityxof the head-rest cushions.

While the invention has beenfshown and described as being composed. of asuitable fabric such as linen. t'oweling stitched along the edges, it isnot the desire to limit the in vention to the precise embodiment shown,but itm'ay be'susceptible to variation-without departing from thespirit, of the invention; For instance, the head-rest cover might becomposed of strong paper folded and pasted along the edges and slit in"the manner described herein. Such a construction would doubtless be muchmore economical and cheaper to manufacture as it would; permitfurnishing a' clean head-rest overro1 each person who mayoccupy thechair,the cover Being discarded after use;

Ifdesired, a' variation in the: construction described herein might beused. in which the head restcover is made by stitching two oblong piecesoffl 'exible material-,suclras linen fabric, together a'longf'our edgesinstead of ma'lfingthe "cover ofa single piece or fabric foldedcentrally. Y

Still another. variation might be used in which a single-slit or openingis provided for accommodating; one of the cushions of the head-rest, thehead-rest cover being made somewhat s maller and adaptedforaccommodating onl'y'one ofthe head-rest cushions.
